Next week is going to be a big week for Windows Phone. We have been told by various sources that Mango will be dropping, and the final tools will be dropping for developers. So that would be interesting and something to look forward to.

The Windows Phone Dev Podcast guys had been pretty accurate with their information previously, being the first to leak screenshots of the “Mango” update as well as correctly predicting the availability dates for the Mango developer betas. This news also seems to coincide nicely with previous clues from WPCentral pointing to a September 15 release date. According to WPCentral, a well-known commercial software company which develops apps for Windows Phone claimed that “the Mango [update] is delayed until September 15”. Support representatives from HTC also mentioned that the Mango update will likely be made available for existing customers “during September”. So, with the BUILD conference starting next Tuesday, it looks to be a huge week next week!
